Answer:
1. The area of a circular table can be calculated using the formula A = πr^2, where A is the area and r is the radius.
A = π(1.5)^2
A = 7.07 square meters
Therefore, the area of the circular table is approximately 7.07 square meters.
2. The area that the cow can graze can be calculated using the formula A = πr^2, where A is the area and r is the radius.
A = π(21)^2
A = 1385.44 square decimeters
Therefore, the cow can graze over approximately 1385.44 square decimeters.
3. The area of the bottom of the fishpond can be calculated using the formula A = πr^2, where A is the area, and r is half of the diameter (i.e., radius).
r = 30/2
r = 15 meters
A = π(15)^2
A = 706.86 square meters
Therefore, approximately 706.86 square meters of cement will be needed to cover the bottom of the pond.
